SIG Quantitative Evaluation practice
1 section · 14 questions · 20 min total
SIG's Quantitative Evaluation is a single typed round of probability, combinatorics, and expected value, with both a calculator and pen and paper allowed.
Style mock based on candidate reports — not official questions; formats change. Compiled from candidate reports on tradinginterview.com, aptitude-test-prep.com (2026).
The timed mock and its single sections come with a LeetQuant membership. The format and sample questions below are free, and so are the 2-minute drills.

|---|---|---|---|---|
| Quantitative Evaluation | 14 | 20 min | +1 right · 0 wrong | Calculator and pen and paper allowed |
About the probability round
The probability section draws from LeetQuant’s own problem bank rather than a generator, so we don’t publish sample answers for it here. Preview the style in the probability interview guide or browse the probability category directly.
